Is it possible to change the behaviour of the preview in browser functionality?

At present, when selecting a different browser it previews straight away. When wanting to switch previews, more apparent if wanting to preview the layout I don't really want it to open a preview straight away as I need to preview the layout.

Could it only preview when clicking on the icon, not on switch? Or something be done for the layout preview? Not a game changer but allow one to keep one's hair longer.
